Air Puppies?

My brother goes to my mom one day holding his hands into a cup, but there was nothing in his hands. Mom asked him what it was and Nate said "I got a puppy!!" Then when my dad comes home, he gets an empty box. When my brother came outside, he saw the box, and he opened it. He reached in to it and when he pulled his out, he said " Another puppy!!" He did that over and over again all day yesterday. Well, today we went outside and I said "I think you should let the puppy go." and he said "NO!!!!!" and he threw himself on the floor and started crying. My brother is so funny and weird.
